Determination method for monitoring points of rolling mill rolling parameters and arrangement structure for rolling mill rolling parameter measuring device for method

Abstract

The invention provides a determination method for monitoring points of rolling mill rolling parameters and an arrangement structure for a rolling mill rolling parameter measuring device for the method. The method comprises the steps that 1, an acceleration sensor and the rolling parameter measuring device are arranged in different positions of a rolling mill at first; and 2, impact factors of the rolling parameters are calculated according to collected data under different passes, and thus the sensitivity size of the rolling parameters is calculated, so that the monitoring points of the rolling mill rolling parameters are rapidly and accurately determined. According to the determination method for the monitoring points of the rolling mill rolling parameters and the arrangement structure for the rolling mill rolling parameter measuring device for the method, other monitoring points of the rolling parameters of the rolling mill except vibration acceleration signals can be rapidly and accurately determined; the rolling force and the rolling speed of a twenty-high rolling mill can be accurately measured, and the set angle of a measuring device for the rolling force and the set angle of a measuring device for the rolling speed are further determined; the measuring accuracy of the rolling force and the rolling speed can be further improved; on the premise that the performance and production of the rolling mill are not affected, on-line precise monitoring on rolling mill vibration is achieved, signals of rolling mill operational states are provided, and normal operation of the rolling mill is ensured.

Description

technical field [0001] The invention relates to a rolling mill vibration monitoring method, in particular to a rolling parameter monitoring and measuring point determination method for a 20-high rolling mill and an arrangement structure of a rolling mill parameter measuring device. Background technique [0002] The rolling mill will vibrate frequently during the rolling process, how to accurately monitor the vibration of the rolling mill has always been a worldwide technical problem. The vibration problem of the rolling mill not only seriously affects the mechanical properties and precision of the rolling mill, but also the strong vibration of the rolling mill will seriously affect the surface quality of the product and bring huge economic losses to the enterprise. Since the rolling mill system has the characteristics of multi-parameters and multi-vibration sources, in order to eliminate the interference of other parameters and obtain more accurate signals during the vibrati...
